Abstract (en)
A heat conducting interface unit (16) for use in mounting an electronic module between cooling plates (40), includes an elongated flexible, U-shaped, highly heat conductive metallic heat exchange member (70) adapted to receive a condensor end (16) of the electronic module. The heat exchange member (70) is located within a housing (60) which provides liquid coolant chambers (61, 62) on the outside walls of the heat exchange member (70). The coolant is supplied under pressure through inlets (63) in the housing (60) from corresponding ports (50) in the cooling plates (40). The pressure in the coolant chamber (61, 62) urges the flexible metallic heat exchange member (70) into increased contact pressure with the condensor portion (16) of the electronic module, reducing the thermal resistance across the contact interface, increasing the rate of heat transfer to the cold plate (40), and clamping the module in position. The heat exchange member (70) covers the entire surface of the condensor (16) to maximize heat transfer. It also provides a simple structure and a short thermal path to the coolant.
